I do not deny that that could be the case. However, whatever happened in those final seconds, the crew did not have time to broadcast anything that was heard before all of those systems failed.
As I said from the beginning, it is purely my opinion based on the data available at the current time.
At some point they are going to get those black boxes and when and if they do, they will tell the tale.
CNN is reporting that 2 of the passengers on the plane, Italy (I can’t remember the other country) it appears that those passports were stolen. As the family of the Italian says his was lost or stolen a year ago and he was issued a new one, and is NOT on that plane.
